device 4 retracted or in its inoperative position. Thereafter, the horse C can be roclied upwardly and downwardly. A yielding stop or spring-pressed buer S is preferably mounted in a lug` 9 on the iront side or the stem so as to form avyielding abutment against which the locking' device -l strilres when the horse is rocked.

iany suitable means'can be used for 'raising and lowering the stem B of the chair and for locking said stem in adjusted position. In the form of my invention herein illustrated the stem B is raised, lowered and locked iu adjusted position by a hydraulic mechanismo't the kind used in Koken harbers chairs and comprising a stationary socket member D in which the stem B slides and a hollowy pump plunger l reciprocatingly mounted inside of the stem D for forcing a liquid from said stem into the space between the bottom or the socket meniber D and the closed louer end the'steni7 the stern. E being` provided in its end-Wall with a valve l1 that opens automatically on the downward stroke or' the pump plunger l0 and said plunger being` provided with a valve l2 that opens on the upward strokeV oi' said plunger and thus permits liquid to enter the space between the under side of said plunger d the ont *wall of the stem'B, it being under tood that the stem B is hollovv and lille-d With oil or other suitable liquid. clamping device l5 that is arranged in an opening in the sine wall ol the stem B is adapted to be 'forced doi-,vn- Wardly into snug engagement with the side Wall of the socket member l) by an inclined surface on the plunger l0 when said plunger p i is moved upwardly a certain distance. l maire no claim to the particuh type or coustruction of the hf'dra'ulic mechanism above described .for ra ing and lov.7 fino' the stem of tl e chair, as said mechanism "as long been in use ano is of the general construction shown in expired U. Patent No. 5411258 to E. E. Koken, dated October Q2, 1895. ln my present chair, however, the device le that actuates the pump plunger l0 is pivotallj7 connected at its upper en@ to acrank arm or bell cranlrlever l5 on the depemling` portion 2 of the plate l that carries the toy animal C, so as to enableV the plunger l0 to actuated b" roei-.ing the a unal .vhich the child sits. rlhis feature adds greatlv to the novelty oll the chair, as thestem B moves vertically when the animal C rocks and thus gives the child the impression that it is due to his eid-forts that the seat oli' the chair is raised or lowered. In the actual operation of the chair the person inchare'e of the chairI grasps the head of the anir al C and limits the degree said animal rocls up and down, as it is necessary that the plunger l0 be moved less than its full strolre during the operation ci raising the stem of the chair.

portion of After the stem has been raised to the required height the person in charge ol the chair mo es the locking member il into engagement With 'the coperating surfaces #land l on tie plate l and on the upper end of the stern B or thechair so as to 'force the rear .end portion ol the plate downwardly into engagement With an inclined surface -lc on the stem, thereby locking the operating mechanism for the stein and also holding the animal C at rest, or, in other we ds, in vsuch a i'nauner i'l'a it can be neither rocked nor revolved.

vThe animal is equipped with a saddle 16 von which the child sits, and il". desired, said position on the saddle, ofthe saddle oi the chair ierein illustrated being provided With dowel pins 17a that lit. in openings in the seat portion of the saddle.

Having thus described my invention, what l claim new and desire to secure by Lotters Patent, is: l

l. A chair of the type referred to, Vcomprising a verticallv-adjustableV support, a to)7 animal mounted on said support in such a manner that it canl be moved relativelj.7 to said support to gir/'e the impression of an animal in motion, and means for causing; aid support to move vertically when said animal moves. Y Y n A chair of the type referred to, com- )rising a vertically-adjustable support, mechanism for raising` and lowering said support, a toy animal rocleablyv mounted on support, and means operated by said zu imal for actuating the invechanisin that raises and lowers the support. l

fr f L"r 'oli the type reerredcto, comprisingl a e, Va vertically-adjustable support moro` on said base, a toy-animal roclrably mounted on said support, mechanism for raising and lowering said support, and operated by the yniorement oi! said animal for actuating said rais ip; and lowering mechanism. 4 Y

A chair of' the type referred to, comprising a ber, a t n reciprocatingly mounted in said member. a hydraulic mechanism lor raisin g and low g said stem, a toy animal roclrabl mounted on sait stem to form a seat for the occupant of the chair, and an actuating device for said'hydraulic .mechanism operated by the movement or" said animal. Y Y

5. A chair of the type referred to, comprising' a vertically-adjustable stem, a. toy anim roclrablj/` mounted on said stem to torri a scatter the occupant-of the chair, mechanism for raising and lowering the stem and for locking'the stem in adjusted position, and means operated by the moveioo los

ment of said animal for actuating said mechanism.

6. A chair of the type referred to, comprising a vertically-adjustable stem, a toy animal rockably mounted on said stem to form a seat for the occupant of the chair, mechanism adapted to be operated by the movement of said animal for raising and lowering the stem, and means under control ef the operator in charge of the chair for preventing said animal from being rocked.

T. A chair of the type referred to, comprising a vertically-adjustable stem, a raising and lowering mechanism for said stem comprising a pump plunger, a rockable member on said stem provided with a lever that is connected to said pump plunger so as to actuate said plunger when said menr ber rocks, and a ohilds toy mounted ou said rockable member to form a seat for the occupant of the chair.

8. A chair of the type referred to, comprising a vertically-adjustable stem, a to \7 animal rockably mounted onsaid stem to form a seat for the occupant of the chair, a

wedge-shaped locking device that is adapted to be interposed between said animal and stem to hold the animal at rest, and means for holding said locking device in an inoperative position when it is desired to rock said animal.

t). A chair of the type referred to, comprising a vertically-adjustable stem, a rockable member at the upper end of said stem provided with a depending portion that is pivotally mounted on said stem, a toy animal ou said rockable member that forms a seat for the occupant of the cha-ir, a crank arm or lever on the depending portion of said rockable member, a mechanism for raising and lowering said stem operatively connected to said crank arm, a wedge-shaped locking device adapted to be interposed between said roclrable member and the upper end of said stem to hold said rockable member at' rest, and an operating rod for said loc :ing device Vjourimled in a bearing` on said rockable member and leading forwardly to the front of said animal.

i0. A chair of the type referred to, comprising a vertically-adjustable stem, a rock.- able member at the upper end of said stem provided with a depending portion that is pivotally mounted on said stem, a toy animal on said roclable member that forms a seat for the occupant of the chair, a cranK arm or lever on the depending portion of said rockable member', a mechanism for raising and lowering said stem operatively connected -to said crank arm, a wedge-shaped locking device adapted to be interposed between sai rockable member and the upper` end of said stem to hold said roclrable member at rest, an operating rod for said locking device journaled in a bearing on said rockable member and leading forwardly to the front of said animal,` a spring arranged on said operating rod between said locking device and the bearing in which said rod is journaled, a cross pin in said rod that is adapted to enter a notch in said bearingwhen said locking device is in its operative position, and a yielding bufiier on said stem for limiting the downward movement of said animal when it is being rocked.
